THIS IMAGE FROM Europe’s Envisat satellite shows the southern part of the Great Barrier Reef off Australia’s Queensland coast. It is the world’s most protected marine area, one of its natural wonders and a World Heritage site.
Spanning more than 2,000 kilometres in length and covering an area of some 350,000 square kilometres, it is the largest living structure on Earth and the only one visible from space.
The image was acquired by Envisat’s Medium Resolution Imaging Spectrometer (MERIS) on 8 November 2010, providing a resolution of 300 metres per pixel.
